The son of Sudanese immigrants who live in a Dallas suburb, the young robotics fan brought in a home-made clock to impress a new teacher at MacArthur High School.

"It was really sad that she took the wrong impression of it and I got arrested," he told reporters last week.

Local police insisted that Mohammed's ethnicity had nothing to do with the decision to arrest him on suspicion of bringing a hoax bomb to school. No charges were laid after it was determined the teen had no malicious intent.

Along with the invitation to astronomy night at the White House next month, Mohamed also got a scholarship to NASA's Space Camp invitations to drive NASA's Opportunity rover, tour MIT and intern at Twitter.

He posted a picture of himself visiting "amazing projects and people" at Google's science fair on his Twitter account, @IStandWithAhmed, Monday.
